比特币或者当下大部分的币都很难用来做为交易的媒介来使用，1.币价波动太大，2.交易费用不稳定，3.币的数量有限量，如果币价可以用来保值的话是不会有人用来它来作为买物的钱，就等于说没有流通性。比特币的发展很可能就是成为一种投资产品，作为钱来使用的可能性越来越低了。

 我也刚想问这个问题。不过可能得问回报率怎么计算，毕竟filecoin还不错细则。

用不用以太做ico和以太的唯一关系就是以太的用户群已近很庞大了。那做的ico好不好和以太本身这个技术是没什么关系的。大部分欧美国家还是对ico比较宽容，只要不踩regulation的红线就可以了。一流技术的ico，比方像ipfs的filecoin它是有资格自己做自己ico的。如果技术类沾边的ico，除非是加深ethereum本身技术的比如Polkadot，那还可以在以太上搞。别的都不是很靠谱。很有可能以太上的ico都会转向资产类，特别是还可以ico的这些国家对ico想要用证券法规去规管。我如果今天发个资产类型的ico，我还是选择ethereum，因为用户群足够大。

作为大家炒的东西来说是越多人知道越好啊。早早入坑的看到你这个标题肯定心里滴血。
作为技术来说不需要太多人知道。就像现在的bitcoin比17年之前参与的人多了不是到多少，也就导致技术升级额各种困难。区块链本身还不成熟，且发展呢。

如果真是的话zf不就立马是自己个自己耳光嘛

ipfs挖矿不就是挖filecoin嘛。连挖矿规则都没出怎么就有矿机了

各方面都要比那个Baikal Giant-N和RR200厉害，就是贵了点。而且感觉没在中国发了，国内网站没看到，有点奇怪。

what do you want to achieve from it? Are you plan to lay out a theory for a new type of blockchain or modifying any existing blockchain?

Hey everyone, this is my post here. Recently, I have a plan to move some miners out of China. At the same time, I am thinking to purchase some new ones.
Most likely, I will buy Avalon 821 and ship them out. I am based in Ontario, so unless there is the way to get them to the US without too much hassle, the group buy is only for Canada for now.
Every 5 miners come with one AUC free. Power Supply Unit and AvalonMiner Controller are purchased separately.

Specifications
Hashrate: 11TH/s, -5% ~ +10%
Power Consumption: 1200W, +0% ~ +20% @ 11TH/s, 25°C, 93% PSU Efficiency, 12V AC, Wall-Plug
Power Efficiency: 0.109J / GigaHash Wall-Plug
Rated Input Voltage: 12 ~ 12.6V
Chips: 104 x A3210 16nm ASIC
Frequency: Smart Speed
PSU output pins: 8 X 6PIN
Network Connection: AUC3 + AUC3 I2C to AvalonMiner Controller: AvalonMiner Controller
AUC3: Up to 5 devices / AUC3, Daisy-Chain Connection
Operating Temperature: -5℃ ~ 30℃
Air-intake Temperature: -5℃ ~ 30℃
Cooling: 1 x 12038 FAN, 6000RPM
Noise: 0 ~ 65db
Dimensions: 370mm x 150mm x 136mm
Gross Dimensions: 430 mm x 215mm x 205mm
Net weight: 4.7kg
Gross weight: 5.2kg

Since I need to ship my own stuff out, I just organize the group by for the community. All the shipping cost, administration fee, duty/tax will be split pro rata. Delivering to your door will be your own cost.
If you are interested, pm me or leave a message below. I want to see if there are enough interests. If there is, I will likely to use escrow account and draft a contract.
This is the first time organizing this type of group buy, so if there is something missing let me know.

美国和加拿大几个地区电费都很便宜，而且相对稳定。而且有需要还可以过去移民定居。
